However, in such a unit building of the above publication, the overhanging members provided on the lower floor unit have a structure that individually supports only the overhang portion of the corresponding upper floor unit. When the floor units are arranged adjacent to each other, there is no cooperative relationship between the support structures of the adjacent overhang portions, so when a horizontal force acts on the unit building, the adjacent overhang portions There is a problem in that a displacement is easily generated between the tip portions of the two.
[0006]
Also, in the case where a structure in which the pillar of the lower floor unit is joined to the lower beam of the upper floor unit, and the end of the horizontal breath material is joined to the pillar of the lower floor unit as a reinforcement of the overhang portion, There is a problem that these intersect to form a complicated structure.
[0007]
Furthermore, if the lower floor unit is joined to the upper floor unit using the wife joint piece, it becomes impossible to join from the outside of the building unit, and it is necessary to cut out the floor plate immediately above the joint. There was a problem that allocation was complicated.
[0008]
Therefore, an object of the present invention is to solve the above-mentioned problems and to provide a fitting for a building unit capable of simplifying the structure and facilitating floor panel layout.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the invention described in claim 1, a building unit that joins a lower-floor building unit and an upper-floor building unit placed in an overhang state on an upper portion of the lower-floor building unit. A joint fitting for a lower-strength column joint that can be joined to a unit pillar upper end side surface of a lower-floor building unit, and an upper-floor lower beam joint that can be joined to a lower beam of an upper-floor building unit. The present invention is characterized by a joint fitting for a building unit integrally provided with a breath material joining portion capable of joining an end of the breath material.
[0010]
According to the invention according to claim 1 configured as described above, the three joining functions of the joining function with the lower story column, the joining function with the upper story lower beam, and the joining function with the breath material are combined into one metal fitting. As a result, the cost can be reduced by simplifying the arrangement. In addition, since the joining operation can be performed from the outside of the building unit, it is not necessary to cut out the floor plate immediately above the joining portion, and the floor plate can be easily allocated.
